This is my first post to the Forums ! Greetings Everyone , going to be all over once I can get my new truck running on its own power. So I was just able to pick up a 1995 F-250 7.3 PS XLT 4x4 5-Speed with a seized motor for dirt cheap. The plan was to swap out the motor another 1997 f-250 7.3 PS , yet I was just told that it is not the same .
So my question is among the 1994-1997 7.3 Power Strokes are there any differences between the years?
I was told I must purchase a motor with the same Calibration for it to match up properly, is that true?
I was able to find a sticker that says Calibration 5-89K-R00 on my motor but was unable to find one on the other 1997 motor.

Welcome to FTE
Welcome to the OBS brethren
The only differences between all 7.3 psd are injectors splitshot vs single shot just swap them out. Super duty have no lobe for the mechanical pump, and front timing cover, hpop pump 15° single shots vs 17° splitshot.
Direct Swap, go for it. Minor differences - water pump, EBPV relocation and HPOP gasket different. Think front timing cover is different between 95 and 97. The 97 will bolt right in.
Another question about the fitment. My 95 is the 5-speed manual and the 1997 is an automatic, will there be any issues there (BOLT Pattern/Bell-housing/PCM) ?

Same bolt patern, will swap right in just remember to swap your flywheel,
Also, the PCM may want to be swapped too. I have heard the auto PCMs can make the engine run weird with a manual. Also while you have the trans open you may want to consider a slightly heavier duty clutch. Just in case you want to squeeze some more power out of it down the road.

There may be a couple of sensors that are different...
Like the ICP - injector control pressure 94-96 and diff for 97
IPr is different too - 1994.5 to 1995.5
oil pan is different
most shouldn't matter though.....

This is exactly why the OP should NOT swap the PCM. The truck is a manual, and should retain the manual PCM. The swap should be considered a swap of the mechanical rotating assembly, retaining as much of the truck's original electronics, accessories, bolt-ons, etc. as possible.
New complete clutch kit and SM flywheel should be a given, to make best use of the effort of the engine R&I. Esp. if the truck is on the original DM flywheel, and since the truck was just purchased, clutch history is probably a major unknown.

That is what I meant to say. It made more sense in my head. Original 95 manual PCM should stay.
Welcome to FTE! As others have said, as long as you leave everything on the '97 engine and drop it in, it will work fine. Don't know if you have pulled one of these engines before or not, but if not, they are VERY heavy. Almost 1000 lbs.! Make sure you have something stout enough to lift it, and if you are gonna put one of them on an engine stand, don't use anything less than a 2000 lb. rated stand. Hate to see anyone get hurt or anything get damaged. Throw up some pics if you get a chance, and congrats and good luck on your new rig!

Okay Great, In regards to the clutch it's being changed along with the master and slave cylinder. From what I got it seems as it should all go as planned, hopefully I won't have to my problems down the line and I'll try my best to snap some photos .
As requested here's a pic of her
Bone stock , she was owned by some construction manger few dings here and there but nothing major .

Thanks for the concern ! I've learned to be careful with diesels in general. Had a Chevy 6.5 bring down my overhead lift ( motor in that tow-truck above photo) . Learned my lesson ... Always use a tractor to pull/swap my engines out now .
